Firing rates

During operation, burner output varies between:
• MAXIMUM OUTPUT must be selected in area A (Fig. 2).
• MINIMUM OUTPUT which must not be lower than the mini-
mum limit in the diagram.
Model MBtu/hr
RS 70/M
RS 100/M
RS 130/M
In order to utilize also area B (RS 130/M) it is necessary to perform
the calibration of the combustion head as explained on page 17.
RS 50/M = 321 MBtu/hr 94 kW
NOTE:
The FIRING RATE areas given in figure (A) have been reduced
by 10% with respect to the maximum range that can be
reached. See "Procedure to refer burner operating condition
at an altitude and/or at a combustion supporter air tempera-
ture different to the standard values (328 ft above sea level, 68
°F)" to page 11 for operation at different ambient temperatures
and/or altitudes.
The firing rate area values have been obtained con-
sidering an ambient temperature of 68 °F, and an
atmospheric pressure of 394" WC and with the
combustion head adjusted as shown at page 17.
